Which one of the following statements is NOT correct porosity rock grains size and shape and mechanical processes

Question-Answer:

Which one of the following statements is NOT correct?

• (a) The porosity of rock depends upon size and shape of the rock grains
  
• (b) Specific gravity is useful for calculating the rock over burden stress
  
• (c) The porosity does not depend on rock mechanical processes
  
• (d) The porosity of spherical rock grains is high in case of cubic packing

Ans. (c)

1
Porosity of a rock depends upon grain size distribution, shape, the presence of cement between the grains developed to different degrees. The porosity of spherical rock grain is high is case of cubic packing.
